I had the same problem with my 92 blazer 140,000+miles and after replacing almost everything in the ignition system I took it to the dealership and they sold me $400 worth of fuel injectors (that I had recently swapped out with aftermarket fuel injectors). The problem persisted and then they found that the wires leading to the fuel injectors were coroaded. They replaced the wiring going to the fuel injectors (for another $60) and I never had the problem again.
